Hepatitis A - children

Definition

Hepatitis A in children is swelling and inflamed tissue of the liver due to the hepatitis A virus (HAV). Hepatitis A is the most common type of hepatitis in children.

Alternative Names

Viral hepatitis - children; Infectious hepatitis - children

Children can get hepatitis A at day care center from other children or from child care workers who have the virus and do not practice good hygiene.

Other common hepatitis virus infections include hepatitis B and hepatitis C. Hepatitis A is typically the least serious and mildest of these diseases.

HAV does not remain in a child's body after the infection is gone. As a result, it does not cause a long-term infection in the liver.

Rarely, a new case can cause severe liver failure that develops rapidly.

Possible Complications

The possible complications of hepatitis A in children can be:
